Functional and sports specific activities depend largely on the range of motion (ROM) available at the employed joints. Early researchers believed that performing static stretches in addition to warm up was important to achieve this ROM, enhance performance and prevent injuries (Belaulieu, 1981; Shellock and Prentice, 1985). However, although its use to improve ROM is well supported by the literature (Harvey et al, 2002, De coste et al. 2005; Radford et al. 2006). Research over the past decade has highlighted that static stretching may decrease performance by up to 30% (Cramer et al., 2005; Fowles, Sale, & MacDougall, 2000; Knudson 2006).

However, conversely to static stretching no studies reported any detrimental effects on strength, power or speed dependent tasks. Several authors have reported increases in ROM without subsequent reduction in isometric strength and dynamic muscle performance (Halperin et al. 2014, Healy et al, 2014; Sullivan et al. 2013). One study found and increase in strength and dynamic performance following a bout of total body foam rolling (Peacock et al, 2014). However, this has not been replicated by further …show more content…
Accordingly, the primary aim of this research project will be to investigate and compare the acute performance related effects of self-myofascial release in the form of foam rolling and static stretching on explosive power, strength and range of motion. The null hypothesis is therefore that there will be no statistical difference between the interventions.
Objectives include:
1) To determine and compare the acute effects of a bout of total body foam rolling and total body static stretching on maximum voluntary force of the Quadriceps, range of motion of the foot, hip and knee and vertical jump performance.
2) To investigate the stretch induced strength and power deficits with stretches of moderate duration.
3) To determine the effect of self-myofascial release in the form of foam rolling and static stretching on delayed onset of muscle soreness,
4) To highlight possible mechanisms underpinning the findings.
